So you consider praying that God makes a lovingly tries to reach out to someone "black magic"?
I like the idea of sugar-coating the concept of a person praying to a powerful entity, to use its power and influence to alter the thoughts of another person, whom had previously stated a stance with which the caster disagrees.
But yes, it's black magic, and gussying it up with the word 'love' does not change that fact.
Unlike the spells that many left handers cast in order to force their will upon someone, the Christian God does no such thing when he's after someone's heart.
Again you keep ignoring the fact that I stated, clearly, it's about the Will of the pray-er, not whatever God thinks. What God thinks is almost irrelevant [and yes, we do have examples IN THE BIBLE mind you, of God influencing a person's thoughts, but Im not interested in that conversation atm].
Your desire, to have God change another person's mind,
your prayer to make this happen, makes it black magic.
However, Christian God ALWAYS gives the person the choice to either ALLOW their heart to be softened or harden it even more.
No, not according to scripture. Ask Pharaoh.
